Cycle on Jun 22, 2026

I am starting the research cycle by listing the open threads of interest for the topic `019e84f4-a5ca-7b52-849a-3dba92371a3c` to see if there are any specific questions or watches already set up by past cycles.

I will now retrieve the existing notes for the topic to see what prior findings we have and how they are structured.

I see several existing notes and a couple of active watches. Let's see what watches we have: 1. `019eca5b-06dc-71df-91ff-8bc240502596`: "DOE Reactor Pilot Program July 4, 2026 Criticality Deadline". The current date in our context is June 22, 2026. This is extremely close (less than two weeks away). Let's see if there are any updates or if other companies have achieved criticality, or if there is news about the DOE Reactor Pilot Program. 2. `019eca5b-10bd-7303-bcb6-37ca0053617b`: "Cameco and Orano Close Cigar Lake Buyout from TEPCO" (expected Q3 2026). 3. `019ea648-6b84-7910-aa5b-6d1378599bba`: "NRC rules on Nano Nuclear's KRONOS Construction Permit Application" (expected 2027). Let's do some research on the latest developments in nuclear energy, focusing on: - Small modular reactors (SMRs) like Oklo, NuScale, Nano Nuclear Energy, and others. - The DOE Reactor Pilot Program and its July 4, 2026 criticality deadline. - Uranium pricing trends (spot and long-term contract pricing). - Utility-level nuclear developments, regulatory moves (NRC, DOE, FERC, etc.), or new PPAs. - Earnings or market updates for companies like CCJ (Cameco), KAP (Kazatomprom), SMR (NuScale), OKLO (Oklo), NNE (Nano Nuclear), CEG (Constellation), VST (Vistra), SO (Southern Company). First, let's pull the market views for some of the key tickers mentioned to ground our analysis in the latest public-markets data. Key tickers: - CCJ (Cameco) - OKLO (Oklo) - NNE (Nano Nuclear Energy) - SMR (NuScale Power) - CEG (Constellation Energy) - VST (Vistra) - SO (Southern Company) Let's start by requesting market views for the key players. I will call `market_view` for `OKLO`, `NNE`, `SMR`, `CEG`, `VST`, and `CCJ`. I can do them one by one or in sequence. I will call them one by one, stating my intent first. I will request the market view for `OKLO` to see its latest financials, valuation, and stock performance.

Interesting. Oklo (OKLO) has recently (June 18, 2026) signed a Letter of Intent (LOI) with Centrus Energy (LEU) to purchase HALEU fuel for up to five of its Aurora powerhouses in Southern Ohio, with deliveries commencing in 2029. This positions Southern Ohio as an advanced nuclear energy hub. Also, on June 16, 2026, Oklo and Standard Nuclear formed a strategic alliance via a Memorandum of Understanding (MOU) to strengthen the advanced nuclear fuel supply chain, focusing on nuclear fuel recycling and advanced fuel. Let's pull the market view for `NNE` (Nano Nuclear Energy) to see its current status.

Excellent. NNE had a Roth Capital coverage initiation on June 17, 2026, with a "buy" rating and a $45 (or $46.25) price target, citing rapid progress toward commercializing its KRONOS microreactor and vertical integration. Let's pull the market view for `SMR` (NuScale Power).

Let's pull market views for the utilities: `CEG` (Constellation Energy) and `VST` (Vistra) to see their performance and latest news.

Now let's pull market views for `VST` (Vistra) and `CCJ` (Cameco).

Let's pull the market view for `CCJ` (Cameco).

Let's do some web searches to find details on these topics: 1. The agreement between Centrus Energy (LEU) and Oklo (OKLO) on June 18, 2026. 2. The agreement between Oklo and Standard Nuclear on June 16, 2026. 3. Nano Nuclear Energy's acquisition of Secured Transportation Services (STS) and Roth Capital's coverage. 4. The DOE Reactor Pilot Program and its July 4, 2026 criticality deadline. Let's search for "DOE Reactor Pilot Program" or "July 4, 2026" or "criticality" or "Antares Nuclear". 5. Uranium spot and long-term contract pricing trends in June 2026. 6. Any other nuclear regulatory developments, NRC decisions, or PPAs in June 2026. Let's do a web search first. We'll search for "Oklo Centrus HALEU June 2026".

Let's fetch the Centrus Energy press release or the World Nuclear News article to get the details of this LOI, including the exact quantities, dates, and terms, and find some quotes. I will fetch `https://www.centrusenergy.com/news/oklo-centrus-sign-letter-of-intent-to-purchase-nuclear-fuel-for-aurora-powerhouse-deployment-in-southern-ohio/` or `https://www.world-nuclear-news.org/articles/centrus-oklo-haleu-agreement-to-support-reactor-deployment`. Let's try the Centrus Energy press release first.

This is a major and highly relevant development. Let's analyze this: - **Date**: June 18, 2026. - **Partners**: Oklo Inc. (NYSE: OKLO) and Centrus Energy Corp. (NYSE: LEU). - **Core agreement**: Non-binding Letter of Intent (LOI) to supply enough domestic high-assay low-enriched uranium (HALEU) to power up to five Aurora powerhouses for multiple years. - **Timeline**: Deliveries to schedule to begin in 2029. - **Location**: Pike County, Ohio (Centrus' American Centrifuge Plant in Piketon). - **Project Scope**: To support Oklo's planned 1.2 GW power campus in Southern Ohio. - **Prepayments**: The agreement could include prepayments from Oklo to Centrus to support fuel supply, following Oklo's January 2026 announcement with Meta (which included prepayments to advance project certainty for the same campus). - **EPC Partner**: Oklo and Kiewit Nuclear Solutions Co. entered into an MOU to support engineering, procurement, and construction (EPC) planning for these initial Aurora deployments. Let's also search for Oklo's alliance with Standard Nuclear on June 16, 2026. Query: "Oklo Standard Nuclear June 2026" or "Oklo Standard Nuclear fuel recycling" Let's run a search.

Let's fetch the article from the American Nuclear Society (ANS) or NucNet or Exchange Monitor to get the details of the Oklo and Standard Nuclear MOU. I will fetch `https://www.ans.org/news/2026-06-17/article-8130/oklo-signs-mou-with-standard-nuclear-to-explore-plutonium-recycling/` or `https://www.nucnet.org/news/oklo-and-standard-nuclear-form-alliance-to-strengthen-us-advanced-nuclear-fuel-supply-chain-6-3-2026`. Let's use the ANS article first.

This is incredibly detailed and useful! Let's analyze this: - **Date**: Wednesday, June 17, 2026. - **Partners**: Oklo Inc. (NYSE: OKLO) and Standard Nuclear (a TRISO fuel fabricator). - **Core agreement**: signed an MOU to explore commercial collaboration on nuclear fuel recycling and advanced fuel manufacturing. - **Significance**: Represents Oklo's first third-party offtake pathway for recycled nuclear materials, including surplus U.S. plutonium. - **Context**: Both companies were selected by the DOE for advanced negotiations under the Surplus Plutonium Utilization Program (SPUP) in late May 2026 (this links to our prior finding `[[doe-surplus-plutonium-program-2026]]`). Under SPUP, five companies (Oklo, Standard Nuclear, Shine Technologies, Flibe Energy, and Exodys Energy) could receive up to 20 metric tons of DOE-owned plutonium (4.4 MT metal and 15.3 MT oxides) to process into fuel. - **Controversy/Criticism**: The program has faced criticism. On June 16, 2026, critics called it a "free ride" for the DOE to dispose of excess weapons-grade plutonium, and a Reuters report on June 15, 2026, highlighted "sky-high security costs" and noted that "highly dangerous plutonium offers no quick fix" for the nuclear fuel crunch. - **MOU Framework**: 1. *Recycled nuclear material offtake*: Supply of reprocessed uranium and uranium-transuranic material streams from spent nuclear fuel from Oklo's planned recycling facility in Oak Ridge, Tennessee, to serve as feedstock for Standard Nuclear's TRISO fuel manufacturing. 2. *Surplus plutonium fuel collaboration*: Jointly explore conversion of surplus plutonium into advanced reactor fuel, collaborating on facilities, licensing, packaging, and transportation. Let's do some more search on Nano Nuclear Energy's acquisition of Secured Transportation Services (STS) and Roth Capital's coverage. Query: "Nano Nuclear Energy Secured Transportation Services Roth Capital June 2026" or "Nano Nuclear Energy STS Roth Capital" Let's search.

Great. Let's fetch some of these articles, specifically: 1. `https://nanonuclearenergy.com/nano-nuclear-acquires-secured-transportation-services-llc-establishing-a-fully-integrated-nuclear-fuel-logistics-and-transportation-platform-and-joining-a-select-group-of-revenue-generating-microreact/` or the Newsfilecorp article: `https://www.newsfilecorp.com/release/299185/Recently-Acquired-NANO-Nuclear-Subsidiary-Secured-Transportation-Services-STS-Completes-Three-DOE-and-NNSA-Aligned-Nuclear-Materials-Transport-Missions` Let's first fetch the Newsfilecorp article to see what Secured Transportation Services (STS) has been doing since the acquisition, and then fetch the Yahoo Finance or Business Insider article about the acquisition itself. Let's do the Newsfilecorp one first since it mentions "three DOE and NNSA-aligned nuclear materials transport missions" which sounds very current.

This is a highly valuable update for Nano Nuclear Energy (NNE). Let's analyze this: - **Acquisition**: Nano Nuclear acquired Secured Transportation Services LLC (STS) in late May 2026 for up to $13 million (approx. $7.1 million cash/stock). - **Recent achievements (announced May 28, 2026)**: 1. *Japan HALEU Transfer*: Served as the DOE's prime logistics contractor to transfer ~1.7 metric tons of HALEU from Japan to the Savannah River Site in South Carolina (noted by NNSA as the largest single international uranium shipment in its history). 2. *Venezuela HEU Removal*: Assisted NNSA in the accelerated removal of 13.5 kg of highly enriched uranium (HEU) from Venezuela's dormant RV-1 research reactor to the Savannah River Site. 3. *Second Domestic HALEU Delivery*: Completed a domestic HALEU transport campaign supporting advanced reactor fuel testing. - **Significance**: By acquiring STS, Nano Nuclear (NNE) has vertically integrated nuclear transportation and logistics capabilities. This supports its subsidiary Advanced Fuel Transportation Inc. (AFT) and positions NNE as an active participant in high-security, DOE and NNSA-aligned nuclear materials transportation. This provides NNE with immediate revenue and operational capabilities while its KRONOS microreactor is still in the licensing phase. Let's do a search on the DOE Reactor Pilot Program and its July 4, 2026 criticality deadline. Query: "Reactor Pilot Program" OR "criticality" OR "Antares Nuclear" "July 4, 2026" OR "July 2026" OR "Idaho National Laboratory". Let's run a search.

Let's check the details of this Reactor Pilot Program. There is a thread: `019eca5b-06dc-71df-91ff-8bc240502596` "DOE Reactor Pilot Program July 4, 2026 Criticality Deadline". The description says: "The Reactor Pilot Program has a fast-approaching criticality deadline of July 4, 2026. Executive Order 14300 originally called for at least three companies to meet the deadline. Antares Nuclear achieved zero-power criticality in early June, and Energy Secretary Chris Wright testified that two more are expected to achieve criticality before July 4, 2026." Let's see if there are any other companies that have achieved criticality or if there's any news. Let's search: `"Reactor Pilot Program" OR "criticality" "July 4, 2026" OR "July 2026"` with freshness `month` or `week` to see if there are any brand new announcements since mid-June. Let's do that!

Oh wow! Look at this: "What's better than one criticality? Two! On June 18, 2026, at around 4:30 MDT, Valar Atomics' Ward 250 test reactor reached criticality in Orangeville, Emery County, Utah!" This is a huge development that directly addresses the active watch `019eca5b-06dc-71df-91ff-8bc240502596` (DOE Reactor Pilot Program July 4, 2026 Criticality Deadline). Let's fetch the Salt Lake Tribune article (`https://www.sltrib.com/news/2026/06/20/utah-reactor-reaches-criticality/`) or the ETV News article (`https://etvnews.com/articles/community/valar-atomics-reaches-criticality-at-ward-250-reactor-in-orangeville/`) or the DOE's official post to get the exact facts and quotes. I will fetch `https://etvnews.com/articles/community/valar-atomics-reaches-criticality-at-ward-250-reactor-in-orangeville/` or `https://www.sltrib.com/news/2026/06/20/utah-reactor-reaches-criticality/`. Let's search for "Valar Atomics" "Ward 250" "Emery County" to get more details or fetch the ETV News article. Let's fetch ETV News first.

This is an incredible development! Let's examine the details of Valar Atomics' achievement: - **Date**: Thursday, June 18, 2026. - **Company**: Valar Atomics (privately held startup, founder and CEO Isaiah Taylor). - **Reactor**: Ward 250 test reactor (high-temperature gas reactor design using TRISO fuel). - **Milestone**: Reached zero-power fueled criticality. - **Significance**: Second advanced reactor to reach criticality under the DOE's Reactor Pilot Program (RPP), following Antares Nuclear's Mark-0 milestone on June 4, 2026. - **Location**: Utah San Rafael Energy Lab in Orangeville, Emery County, Utah. (Described as the first DOE-authorized reactor built outside a national laboratory). - **Transport**: Components were flown from California to Hill Air Force Base aboard U.S. Air Force C-17 aircraft before being moved to the Orangeville-area test site. - **Next Target**: Begin power operations by July 4, 2026. - **Program context**: Under the Reactor Pilot Program, the DOE set a goal of having at least three advanced reactor concepts reach criticality by July 4, 2026. With Antares (June 4) and Valar (June 18) both achieving this, the program is very close to meeting its goal. We need to see if a third company is about to achieve criticality. Let's see if there is any news on who the third company might be. The thread description says: "Antares Nuclear achieved zero-power criticality in early June, and Energy Secretary Chris Wright testified that two more are expected to achieve criticality before July 4, 2026." Valar Atomics is one of them. Let's search for "Reactor Pilot Program" third company OR "criticality" "July 4, 2026" to see if we can find who the third company is. Let's run a search.

Let's search for "three advanced reactor designs" "criticality" "July 4, 2026" or "Unity microreactor" since it mentioned "Unity microreactor clears safety hurdle" and "criticality testing later this summer" in the previous search. Let's search: `"Unity microreactor" "criticality"` or `"Unity" "criticality" "July 4, 2026"`. Let's do that.

Let's do a search on other companies in the Reactor Pilot Program that might be close or if there is a third company. Let's search: `"Reactor Pilot Program" OR "criticality" "July 4, 2026" OR "July 2026" "third"` or `"three"` or `"another"`. Let's see: we have Antares Nuclear (Mark-0, achieved criticality June 4, 2026) and Valar Atomics (Ward 250, achieved criticality June 18, 2026). Who are the other companies in the Reactor Pilot Program? Let's search for "Reactor Pilot Program" "projects selected" or "11 projects". Let's run a search.

Let's fetch the ANS article "The progress so far: An update on the Reactor Pilot Program" (`https://www.ans.org/news/2025-11-14/article-7543/the-progress-so-far-an-update-on-the-reactor-pilot-program/`) or see what other information we can find about the companies. Let's do a quick search on "The progress so far: An update on the Reactor Pilot Program" to see if there is another company close to criticality. Query: "The progress so far: An update on the Reactor Pilot Program" Or let's search for "Oklo" and "Reactor Pilot Program" to see if Oklo is part of it and if it's close to criticality. Let's search.

Let's see if Oklo's "Groves Isotope Test Reactor" or "Atomic Alchemy" is close to criticality. Let's do a web search on Oklo's Groves Isotope Test Reactor and see its status. Query: `"Groves Isotope Test Reactor" OR "Atomic Alchemy" "criticality" OR "July 4, 2026" OR "June 2026"` Let's search.

Ah, the web_search budget is spent. No problem, we have got plenty of rich, detailed information from our search results and market views. Let's review what we have: 1. **The DOE Reactor Pilot Program July 4, 2026 Criticality Deadline (Watch ID: `019eca5b-06dc-71df-91ff-8bc240502596`)**: - **Antares Nuclear** achieved zero-power criticality on June 4, 2026, with its Mark-0 reactor at Idaho National Laboratory. - **Valar Atomics** achieved zero-power criticality on June 18, 2026, with its Ward 250 test reactor at the Utah San Rafael Energy Lab in Orangeville, Emery County, Utah. This is the second reactor in the program to reach the milestone. - **Oklo's Atomic Alchemy** (wholly owned subsidiary of Oklo Inc.) is targeting criticality for its Groves Isotope Test Reactor in Lockhart, Caldwell County, Texas, before the July 4, 2026 deadline. - This represents a massive milestone for the advanced nuclear sector, with two reactors already achieving criticality in June 2026, and Oklo's Groves reactor racing to be the third by the July 4, 2026 deadline. - Since the deadline is July 4, 2026, which is in the future relative to our current date (June 22, 2026), this watch (`019eca5b-06dc-71df-91ff-8bc240502596`) is still active and ongoing until July 4, 2026. However, we can record that a significant event occurred! Wait, `record_event` is for when a watch has fired (either resolved or ongoing). Let's see: the watch is "DOE Reactor Pilot Program July 4, 2026 Criticality Deadline", and the trigger is "Monitor for announcements of other advanced nuclear companies (such as Oklo or other participants) achieving criticality at INL by the July 4, 2026 deadline." - Valar Atomics achieved criticality on June 18, 2026, and Antares on June 4, 2026. This is exactly what the watch was tracking! Let's record this event. Since the July 4, 2026 deadline hasn't fully passed and we are waiting to see if a third company (like Oklo's Atomic Alchemy) achieves criticality too, we can record the event with `resolves: false` to keep the watch open, or we can resolve it if the watch was just to monitor for other companies achieving criticality. The cardinality of the watch is `one_shot` (meaning it closes once fired/resolved), but the fire date is July 4, 2026. Let's record the event on the thread `019eca5b-06dc-71df-91ff-8bc240502596` with `resolves: false` or `resolves: true` depending on if we want to close it. Since we want to keep tracking until the July 4, 2026 deadline (to see if a third reactor, like Oklo's Groves, goes critical), we should set `resolves: false` so it stays open for the next cycle (which will probably run after July 4). Let's do that! 2. **Oklo's Strategic Advancements and Nuclear Fuel Supply Chain**: - On June 18, 2026, Oklo (OKLO) and Centrus Energy (LEU) announced a major non-binding Letter of Intent (LOI) to supply HALEU fuel for up to five of Oklo's Aurora powerhouses for multiple years, with deliveries starting in 2029. This supports Oklo's planned 1.2 GW power campus in Southern Ohio. Prepayments from Oklo are anticipated. This is a critical commercial step addressing the sector's HALEU bottleneck. - On June 16, 2026, Oklo signed an MOU with Standard Nuclear (a TRISO fuel fabricator) to explore commercial collaboration on nuclear fuel recycling and advanced fuel manufacturing. This represents Oklo's first third-party offtake pathway for recycled materials from its planned facility in Oak Ridge, Tennessee, including surplus U.S. plutonium from the DOE's Surplus Plutonium Utilization Program (SPUP). - These developments are highly relevant to Oklo's regulatory milestones, fuel supply, and commercial pathways, expanding on: - `[[oklo-regulatory-milestones-vertical-integration-2026]]` - `[[doe-surplus-plutonium-program-2026]]` - `[[meta-oklo-smr-power-campus-2026]]` - Let's update `oklo-regulatory-milestones-vertical-integration-2026` with these major June 2026 updates! 3. **Nano Nuclear Energy (NNE) Vertical Integration and Roth Capital Buy Rating**: - Nano Nuclear Energy (NNE) was initiated with a "Buy" rating and a $45 (or $46.25) price target by Roth Capital on June 17, 2026, citing rapid progress toward commercializing its KRONOS microreactor and vertical integration. - NNE's late-May 2026 acquisition of Secured Transportation Services (STS) for up to $13 million is already bearing fruit. On May 28, 2026, NNE announced that STS completed three high-profile DOE and NNSA-aligned nuclear transport missions: 1. The historic transfer of ~1.7 metric tons of HALEU from Japan (the largest single international uranium shipment in NNSA history). 2. Supporting the removal of 13.5 kg of highly enriched uranium (HEU) from Venezuela's dormant RV-1 research reactor. 3. A domestic HALEU delivery for advanced reactor fuel testing. - This vertical integration gives NNE immediate operational capabilities and revenue, making it a unique player in the pre-revenue advanced nuclear space. - This updates `[[nano-nuclear-energy-nrc-milestone-2026]]`. Let's record the event on the watch first. The thread ID is `019eca5b-06dc-71df-91ff-8bc240502596` ("DOE Reactor Pilot Program July 4, 2026 Criticality Deadline"). Let's call `record_event`. I will state my intent first. I will record the event for the DOE Reactor Pilot Program watch, noting that both Antares Nuclear (June 4) and Valar Atomics (June 18) have achieved zero-power criticality, bringing the program very close to its July 4, 2026 target of having three reactors achieve criticality. I will keep the watch open (`resolves: false`) as we await the third reactor (such as Oklo's Groves Isotope Test Reactor) to go critical before July 4, 2026.

Now let's write or update our notes. First, let's review our notes that we need to update: - `oklo-regulatory-milestones-vertical-integration-2026`: We want to update this note to include Oklo's June 18, 2026 LOI with Centrus Energy for HALEU supply and its June 16, 2026 MOU with Standard Nuclear for fuel recycling / plutonium offtake. - `nano-nuclear-energy-nrc-milestone-2026`: We want to update this note to include Nano Nuclear's late-May 2026 acquisition of Secured Transportation Services (STS), the successful DOE/NNSA transport missions announced on May 28, 2026, and the Roth Capital "Buy" rating initiation on June 17, 2026. - Let's create a new note or update an existing note for the Reactor Pilot Program. Wait, do we have an existing note on the Reactor Pilot Program? Let's check `read_notes` results. The existing notes are: 1. `oklo-regulatory-milestones-vertical-integration-2026` 2. `nano-nuclear-energy-nrc-milestone-2026` 3. `uranium-pricing-supply-constraints-2026` 4. `doe-surplus-plutonium-program-2026` 5. `constellation-ferc-waiver-three-mile-island-2026` 6. `nuscale-power-legal-troubles-entra1-2026` 7. `meta-vistra-nuclear-ppa-2026` 8. `meta-oklo-smr-power-campus-2026` 9. `constellation-energy-secondary-offering-2026` There is no dedicated note for the Reactor Pilot Program yet. Let's write a new note for the Reactor Pilot Program and the race to criticality by July 4, 2026. Let's name the slug for this new note: `doe-reactor-pilot-program-criticality-race-2026`. Wait, let's make sure we ground everything in concrete evidence, including our market views and web fetch findings, naming and linking the actual sources, and carrying verbatim quotes. First, let's read the existing note `oklo-regulatory-milestones-vertical-integration-2026` so we can update it properly without losing prior context. I will write a note with the same slug `oklo-regulatory-milestones-vertical-integration-2026` to update it. Let's see what is currently in `oklo-regulatory-milestones-vertical-integration-2026` by searching or reading it if there is a way. Oh, we don't have a direct "read_note" tool, but we can search or we can reconstruct it from the preview or we can write a comprehensive updated note. Since we have the preview, let's look at it: "In June 2026, Oklo Inc. (NYSE: OKLO) achieved two major operational and regulatory milestones, advancing its fast-fission reactor commercialization pathway and bringing critical nuclear component..." Let's see if we can find the full content of `oklo-regulatory-milestones-vertical-integration-2026` by searching our workspace. Oh, wait, the workspace is at `/var/lib/hey-lefty/notes/9a44a098-76c7-4569-9018-23a27f9ebd7f/019e84f4-a5ca-7b52-849a-3dba92371a3c`. Let's check if there are markdown files in that directory that we can read. Yes, we can read files in our workspace! Wait, let's list the files in the workspace or find where the notes are stored. Let's check using standard shell commands or see if there is a tool. Ah, we don't have a shell tool exposed in our declarations. We only have: - `list_threads` - `record_thread` - `resolve_thread` - `record_watch` - `record_event` - `read_notes` - `write_note` - `web_search` - `web_fetch` - `market_view` - `finish_cycle` Wait, since we don't have a file system reading tool, let's write the complete updated note for `oklo-regulatory-milestones-vertical-integration-2026` using the new information we gathered from `market_view` and `web_fetch`. Let's check the market view of `OKLO` again. - Market capitalization: $10.64B (as of June 22, 2026). - Net loss: $33.1 million for Q1 ending March 31, 2026. - Cash position: $1.59 billion against $2.6 million in total debt. - Recent developments: - Letter of Intent with Centrus Energy Corp. (NYSE: LEU) on June 18, 2026, to supply HALEU fuel for up to five Aurora powerhouses in Southern Ohio starting in 2029. - MOU with Standard Nuclear on June 16, 2026, to explore commercial collaboration on nuclear fuel recycling and advanced fuel manufacturing. - Oklo's subsidiary Atomic Alchemy is targeting criticality for its Groves Isotope Test Reactor in Texas before the July 4, 2026 deadline under the DOE Reactor Pilot Program. Let's write the updated note for Oklo. I will call `write_note` with the slug `oklo-regulatory-milestones-vertical-integration-2026`. I will state my intent first. I will write the updated note for Oklo's regulatory milestones and vertical integration (slug: `oklo-regulatory-milestones-vertical-integration-2026`). This note will integrate the latest June 18, 2026 Centrus Energy HALEU supply LOI and the June 16, 2026 Standard Nuclear recycling MOU, grounding the financial data in the latest `/markets/OKLO/2026/06/22` market view and quoting from the primary sources we fetched.

Excellent. Now let's write the note for the DOE Reactor Pilot Program and the race to criticality by July 4, 2026. Let's name the slug: `doe-reactor-pilot-program-criticality-race-2026`. We have detailed facts on: - Antares Nuclear's Mark-0 reactor achieving zero-power criticality on June 4, 2026, at Idaho National Laboratory. - Valar Atomics' Ward 250 test reactor achieving zero-power criticality on June 18, 2026, in Orangeville, Emery County, Utah. This is the first DOE-authorized reactor built outside a national laboratory (at the Utah San Rafael Energy Lab). - Oklo's Atomic Alchemy Groves Isotope Test Reactor targeting criticality before the July 4, 2026 deadline. - The overarching goal of the Reactor Pilot Program is to have at least three advanced reactors go critical by July 4, 2026, under a streamlined DOE authorization process separate from standard NRC commercial licensing. Let's write this finding note. I will call `write_note` for the Reactor Pilot Program. I'll state my intent first. I will write a new note for the DOE Reactor Pilot Program's race to criticality (slug: `doe-reactor-pilot-program-criticality-race-2026`). This note will detail the achievements of Antares Nuclear and Valar Atomics, as well as the upcoming target for Oklo's Atomic Alchemy, quoting directly from the primary sources we fetched.

Great. Now let's update the note for Nano Nuclear Energy (NNE). The current note is: `nano-nuclear-energy-nrc-milestone-2026` ("Nano Nuclear Energy Microreactor Design Reaches Key Regulatory Milestone with NRC"). Let's see what is in the preview: "In mid-2026, Nano Nuclear Energy Inc. (NASDAQ: NNE) accelerated its strategy to become a highly integrated, vertically structured advanced nuclear company, combining proprietary microreactor designs..." We want to update this note to include: - NNE's late-May 2026 acquisition of Secured Transportation Services (STS) for up to $13 million. - The major STS-executed nuclear logistics missions announced on May 28, 2026: 1. Transferring ~1.7 metric tons of HALEU from Japan (the largest single international uranium shipment in NNSA history) to the Savannah River Site. 2. Supporting the removal of 13.5 kg of highly enriched uranium (HEU) from Venezuela's dormant RV-1 research reactor. 3. A domestic HALEU delivery for advanced reactor fuel testing. - The financial context of NNE from the latest market view: - Market cap: $1.47B (as of June 22, 2026). - Cash position: $197.7 million against $2.6 million in total debt as of March 31, 2026. - Quarterly trajectory: Pre-revenue, with an operating loss of $14.1 million for the quarter ending March 31, 2026. - Buy rating initiation by Roth Capital on June 17, 2026, with a $45 (or $46.25) price target, citing rapid progress toward commercializing its KRONOS microreactor and its vertical integration strategy. Let's write this updated note. I will call `write_note` for NNE. I'll state my intent first. I will write the updated note for Nano Nuclear Energy (slug: `nano-nuclear-energy-nrc-milestone-2026`). It will integrate the late-May acquisition of Secured Transportation Services (STS) and the high-profile DOE/NNSA shipping campaigns, along with the Roth Capital coverage initiation, grounded in the `/markets/NNE/2026/06/22` market view.

Let's double check if we need to record any new watches or threads. Let's see: we have recorded the event on the active thread `019eca5b-06dc-71df-91ff-8bc240502596` ("DOE Reactor Pilot Program July 4, 2026 Criticality Deadline"), which keeps it open. Is there any new forward-looking catalyst or tripwire we should register as a watch? - **Oklo's Groves Isotope Test Reactor (Atomic Alchemy)**: This is already covered under the Reactor Pilot Program watch (`019eca5b-06dc-71df-91ff-8bc240502596`), which tracks if Oklo or other participants achieve criticality by the July 4, 2026 deadline. - **Oklo's next financial update**: The search results mentioned that Oklo is slated to provide its next financial update on August 10, 2026 (estimated). - **NuScale Power (SMR)**: We pulled its market view, which showed a 22.7% rebound over the past 5 days to $11.74, but it continues to face severe revenue declines (-95.8% YoY TTM revenue of $18.7M) and quarterly losses ($44M net loss in Q1 2026). However, there are no specific new dated catalysts or tripwires for SMR that we need to register right now. - **Cameco and Orano's buyout of TEPCO's 5% stake in Cigar Lake**: This is already tracked by watch `019eca5b-10bd-7303-bcb6-37ca0053617b` (expected Q3 2026). - **KRONOS microreactor construction permit application**: This is already tracked by watch `019ea648-6b84-7910-aa5b-6d1378599bba` (expected 2027). Wait, let's look at the watch `019eca5b-06dc-71df-91ff-8bc240502596` again. The fire date is `2026-07-04T00:00:00Z`. Since the deadline is July 4, 2026, let's keep it open. In the next cycle, which will likely run after July 4, 2026, the assistant will check if Oklo or other participants completed their criticality and then resolve the watch. Let's see if we should create a new watch. What about Oklo's definitive agreement with Centrus? The LOI was announced on June 18, 2026. A definitive agreement is expected to be negotiated. However, there is no specific date for it yet, so we don't need a dated watch. Let's check if there are any other open threads that we can resolve. Let's look at the threads listed by `list_threads`: - `019eca5b-10bd-7303-bcb6-37ca0053617b`: "Cameco and Orano Close Cigar Lake Buyout from TEPCO" (watch, expected Q3 2026). Not resolved yet. - `019eca5b-06dc-71df-91ff-8bc240502596`: "DOE Reactor Pilot Program July 4, 2026 Criticality Deadline" (watch, expected July 4, 2026). Not resolved yet, as the July 4 deadline is still in the future, though we recorded a major event. - `019ea648-6b84-7910-aa5b-6d1378599bba`: "NRC rules on Nano Nuclear's KRONOS Construction Permit Application" (watch, expected 2027). Not resolved yet. So there are no threads to resolve in this cycle. Let's verify if all our notes are well-formed and follow the guidelines: - Title is the first `#` heading. - No YAML frontmatter. - Use wikilinks for other findings: `[[doe-reactor-pilot-program-criticality-race-2026]]`, `[[oklo-regulatory-milestones-vertical-integration-2026]]`, `[[meta-oklo-smr-power-campus-2026]]`, `[[doe-surplus-plutonium-program-2026]]`, `[[nrc-rules-on-nano-nuclears-kronos-construction-permit-application]]`. - Grounded in concrete evidence with verbatim quotes and links in the `## Sources` block. - Title and slug are stable and durable (not transient "story-of-the-day" style). - Cite the `/markets` URLs for any quantitative claims or market views used. Wait, let's review if there are any other wikilinks we should fix or add. In `oklo-regulatory-milestones-vertical-integration-2026`, we linked to: - `[[meta-oklo-smr-power-campus-2026]]` - `[[doe-surplus-plutonium-program-2026]]` - `[[doe-reactor-pilot-program-criticality-race-2026]]` In `doe-reactor-pilot-program-criticality-race-2026`, we linked to: - `[[oklo-regulatory-milestones-vertical-integration-2026]]` In `nano-nuclear-energy-nrc-milestone-2026`, we linked to: - `[[nrc-rules-on-nano-nuclears-kronos-construction-permit-application]]` (Wait, let's make sure the slug matches the watch or notes. Let's check `list_threads` results: the watch title is "NRC rules on Nano Nuclear's KRONOS Construction Permit Application" and its thread ID is `019ea648-6b84-7910-aa5b-6d1378599bba`. Oh, wait! The slug for this is actually not in `read_notes` yet, as it's just a watch thread. Let's make sure we don't break links. If there is no note with that slug yet, a wikilink won't resolve correctly if the note doesn't exist, but it's fine if the note is created later. Wait, let's see if we have a note for KRONOS. Yes, we updated `nano-nuclear-energy-nrc-milestone-2026` which is the main note for NNE's KRONOS microreactor and vertical integration. So we can just link to `[[nano-nuclear-energy-nrc-milestone-2026]]` or keep the wikilink to the watch thread slug if we want, but it's better to link to existing notes.) Let's see: `nrc-rules-on-nano-nuclears-kronos-construction-permit-application` is a watch thread title, not a note slug. The note slug is `nano-nuclear-energy-nrc-milestone-2026`. So we should link to `[[nano-nuclear-energy-nrc-milestone-2026]]` instead of `[[nrc-rules-on-nano-nuclears-kronos-construction-permit-application]]`. Let's modify `nano-nuclear-energy-nrc-milestone-2026` to remove the self-link if we had one, or let's verify. In `nano-nuclear-energy-nrc-milestone-2026` we wrote: `with the NRC's safety and environmental reviews estimated to conclude in 2027 [[nrc-rules-on-nano-nuclears-kronos-construction-permit-application]].` Since `nrc-rules-on-nano-nuclears-kronos-construction-permit-application` is not a note slug, let's rewrite that part or make sure it doesn't break. Wait! We can just leave it as text or we can create a note for it, but since we updated `nano-nuclear-energy-nrc-milestone-2026` which already covers KRONOS and its regulatory milestones, we don't need a separate note. Let's revise `nano-nuclear-energy-nrc-milestone-2026` to remove the wikilink to the non-existent note, or we can just keep it as text. Let's call `write_note` again to refine it. I will state my intent first. I will revise the `nano-nuclear-energy-nrc-milestone-2026` note to remove the wikilink to the non-existent note, ensuring clean and valid wikilinks in our living documentation.

Excellent. I have updated the two existing notes and created one new note. Let's review the notes we have written or updated: 1. `oklo-regulatory-milestones-vertical-integration-2026`: Updated with the Centrus Energy LOI for HALEU supply (June 18, 2026) and the Standard Nuclear MOU for plutonium/TRISO fuel recycling (June 16, 2026). 2. `nano-nuclear-energy-nrc-milestone-2026`: Updated with the late-May acquisition of Secured Transportation Services (STS), the successful DOE/NNSA transport missions announced on May 28, 2026, and the Roth Capital "Buy" rating initiation on June 17, 2026. 3. `doe-reactor-pilot-program-criticality-race-2026`: Created a new note to track the progress of the DOE Reactor Pilot Program and its July 4, 2026 criticality deadline, detailing Antares Nuclear's June 4 criticality and Valar Atomics' June 18 criticality. I have also recorded a major event on the active watch `019eca5b-06dc-71df-91ff-8bc240502596` ("DOE Reactor Pilot Program July 4, 2026 Criticality Deadline"), keeping it open as we await further developments (such as Oklo's Atomic Alchemy criticality) before the July 4, 2026 deadline. Everything is complete. I will call `finish_cycle` to end the research cycle. I will state my intent first. I will now call `finish_cycle` to conclude this research cycle, as all findings have been written, updated, and logged, and the active watch has been updated with the latest event.

I have successfully completed this research cycle for topic `019e84f4-a5ca-7b52-849a-3dba92371a3c` (resurgence of nuclear energy across public markets). Here is a summary of the key findings and updates persisted during this cycle: ### 1. The Criticality Race: DOE Reactor Pilot Program * **Finding Created**: `[[doe-reactor-pilot-program-criticality-race-2026]]` * **Summary**: The U.S. Department of Energy’s (DOE) Reactor Pilot Program (RPP) is seeing rapid operational success as advanced nuclear startups race to meet the federal **July 4, 2026** criticality deadline. * **Antares Nuclear** completed a zero-power fueled criticality test for its Mark-0 demonstrator microreactor at Idaho National Laboratory on **June 4, 2026**. * **Valar Atomics** achieved zero-power fueled criticality with its Ward 250 test reactor (high-temperature gas reactor using TRISO fuel) on **June 18, 2026**, at the Utah San Rafael Energy Lab in Orangeville, Utah—marking the first DOE-authorized reactor built and operated outside a national laboratory. * **Oklo's Atomic Alchemy** is actively preparing its Groves Isotope Test Reactor in Lockhart, Texas, to be the third reactor to achieve criticality before the July 4, 2026 deadline. * **Watch Tracking**: Recorded a major event on the active watch `019eca5b-06dc-71df-91ff-8bc240502596` while keeping it open (`resolves: false`) to monitor the final stretch of the July 4 deadline. ### 2. Oklo's Commercial Expansion: Fuel Supply and Recycling Agreements * **Finding Updated**: `[[oklo-regulatory-milestones-vertical-integration-2026]]` * **Summary**: Oklo Inc. (NYSE: OKLO) has significantly strengthened its vertical integration model with two major partnerships in mid-June 2026: * **Centrus Energy LOI (June 18, 2026)**: A Letter of Intent under which Centrus (NYSE: LEU) will supply domestically enriched HALEU fuel from its Piketon, Ohio plant to power up to five of Oklo's Aurora powerhouses starting in 2029 (supporting its planned 1.2 GW Ohio Clean Energy Campus). Prepayments from Oklo are anticipated, following the model established in its January 2026 Meta PPA. * **Standard Nuclear MOU (June 16, 2026)**: An agreement with TRISO fuel fabricator Standard Nuclear to establish Oklo's first third-party offtake pathway for recycled nuclear materials (including reprocessed uranium and uranium-transuranic streams) from its Oak Ridge, Tennessee facility, and to collaborate on converting surplus U.S. plutonium under the DOE's Surplus Plutonium Utilization Program (SPUP) [[doe-surplus-plutonium-program-2026]]. * **Markets Context**: Graphed against the latest `/markets/OKLO/2026/06/22` view, Oklo's $10.64B market cap is backed by $1.59B in cash (against just $2.6M in total debt as of March 31, 2026), giving it ample liquidity to fund these capital-intensive fuel and construction commitments. ### 3. Nano Nuclear Energy: Logistics Revenue and Wall Street Recognition * **Finding Updated**: `[[nano-nuclear-energy-nrc-milestone-2026]]` * **Summary**: Nano Nuclear Energy Inc. (NASDAQ: NNE) is executing an aggressive vertical integration strategy that is already yielding operational results and Wall Street recognition: * **Secured Transportation Services (STS)**: NNE's late-May $13M acquisition of STS is already active. On **May 28, 2026**, NNE announced that STS completed three high-profile, federally aligned nuclear logistics missions: 1. Serving as prime contractor for the transfer of ~1.7 metric tons of HALEU from Japan (the largest single international uranium shipment in NNSA history). 2. Supporting the NNSA's accelerated removal of 13.5 kg of highly enriched uranium (HEU) from Venezuela's dormant RV-1 research reactor. 3. Completing a domestic HALEU transport campaign supporting advanced reactor fuel testing. * **Roth Capital Buy Rating (June 17, 2026)**: Roth Capital initiated coverage on NNE with a "Buy" rating and a $45.00 (or $46.25) price target, citing its unique vertical integration (spanning reactor design, fuel fabrication, and logistics) and rapid commercial progress. * **Markets Context**: Grounded in the `/markets/NNE/2026/06/22` view, NNE maintains a market cap of $1.47B and a strong liquid position of $197.7M in cash (against $2.6M in debt as of March 31, 2026), mitigating its pre-revenue operating loss of $14.1M. All findings have been saved to the topic's living documentation, and the active threads and upcoming catalysts remain carefully tracked. I am ready for the next cycle!
